Anyone else? Won’t find the device at all. Works with iPhone instead.
Took me quite a while but I got it to work again. Had to reset the Bluetooth module a few times (fun when you’re on a wireless mouse…). It finally found it again and I was able to pair. Had to reenter the 4-digit code.
You reset bluetooth by holding down Shift-Option and click on the bluetooth symbol at the top. Submenu: Debug, then first “remove” and then “reset”. Always a good idea to have everything backed up when installing “updates” and messing with settings like this.
